The invention relates to a method for bringing about the transformation of a medium (1) such as carbon dioxide or other gases or mixtures thereof into snow (2). In accordance with the invention, the aforementioned medium (1) and the snow (2) produced from it are caused to interact with surfaces of a snow-producing nozzle (4 2) extending from a discharge orifice (3) for the medium (1). The aforementioned medium (1), after exiting from the discharge orifice (3), is either permitted to expand into an elongated space which exhibits a uniform cross section. Or the medium (1) is also permitted to act against a number of obstructions (10, 11) in the form of flexible bristles (13) situated along the flow path of the medium as it flows out between the discharge orifice (3) for the medium (1) and an outlet (12) for the formed snow (2). The produced carbon dioxide snow (2) is intended for use in small animal pest decontamination. Means for producing snow (2) are included in the invention.
La présente invention concerne un procédé de transformation d'un milieu (1) tel que le dioxyde de carbone ou d'autres gaz, ou des mélanges de ces gaz, en neige (2). Le milieu (1) mentionné et la neige (2), à partir duquel elle est produite, sont amenés à interagir avec des surfaces d'une buse (4<2>) à production de neige qui s'étendent d'une ouverture de décharge (3) du milieu (1). Après sa sortie de l'ouverture de décharge (3), le milieu (1) ou bien s'expanse à l'intérieur d'un espace allongé de section transversale uniforme, ou se heurte à un certain nombre d'obstructions (10,11), qui ont la forme de poils souples (13), placées le long du chemin suivi par le milieu entre l'ouverture de décharge (3) et la sortie (12) de la neige formée. La neige carbonique formée est destinée à la destruction des petits parasites d'animaux. La présente invention concerne aussi des moyens destinés à produire ladite neige (2).
